ELECTROMAGNETIC BRAIDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 591,105, dated October 5, 1897.

Application filed March 2, 1896.

reference marked thereon, which form a part of this specification. I

This invention, hereinafter f ullydescribed,

reference being had by letters to the drawings herewith, is of the character used in the manufacture of woven tubular fabrics and for the covering ofwire by interwoven or crossing strands.

The principal object sought to be accom plished in a weaving-machine of this kind, 'but better known as a braiding-machine,

is the alternate crossing and spiral winding of the threads, thereby causing the latter to interlap and form a tubular .web as the Weaving continues, and to do this in a uniform manner and at a rapid speed. 7 Each of the threads comprising the weave are made to pass over and under each alternate thread, so that the thread selected to pass over a certain thread will pass over the same thread each; time it meets it in its directly opposite movement.

In order to properly braid the threads on this machine and insure the production of a perfect fabric, it is essential that the number of threads employed be divisible by two, so that the sets of threads shall pass each other during the braiding operation at the proper intervals.

The machines at present employed forthe manufacture of braids or similar forms of weave, while not only very expensive to construct and extremely intricate in number of parts, are not capable of being run at any high rate of speed in order to manufacture rapidly fabric or covering of the classes mentioned.

The form of machine most in use at present Serial No. 581,490. (No model.)

employs Vertical bobbins mounted upon peculiarly-constructed carriages that are made to traverse in directly opposite directions a tortuous slot or passage-way between stationary plates by means of a train of gearwheels concentric with the weave, and each separate gear is provided with wings or projections that engage the stem of the bobbincarriage and by means of the slot or tortuous passageway propels the bobbin marriages past each alternate bobbin. It will be readily understood that by using such a train of gearwheels, aside from the friction of the bobbincarriages in the slot, it will require a great expenditure of power to drive such a machine, and it is also at once apparent'that but an exceedingly slow rotary motion of the two directly oppositely moving set of bobbincarriages can be attained.

Other machines have also been designed to overcome these defects, but as far as I am able to learn intricate construction and the use of multiplex devices more or less liable to get out of order have not to any appreciable extent remedied the troubles aside from being very expensive to build, so that any and all of the machines as now constructed and used have their faults, and, as before stated, the most important of which is the low speed at which they can be run and their limited amount of product.

In my invention cheapness of construction, simplicity of parts, and speed are its principal advantagesmhile by the use of the agency of magnetism the operations of the machine are positive and automatic, while little, if any, attention is required on the part of the operator.

I shall now proceed to describe the Various views of the machine and its parts on the several sheets of the accompanying drawings, and shall hereinafter refer to them. by referonce-letters in describing the construction and operation of the machine.

Figure 1 is afront elevation of the machine, showing the several rotating parts mounted in the framework. Fig. 2 is a top or plan view of the same, also showing the connections between the contact-plates and the source of electrical supply. Fig. 3 is a view of the side of the machine, illustrating the shape of the two directly opposite standards comprised in the framework supporting all the parts, journaled in the top of which standards is the drive-shaft and the shaft carrying the drag-wheel for the manufactured product, together with the insulated contactplates and contact springs on the several standards of the frame. Fig. at is a top View of one of the non-magnetic toothed shells carrying the bobbins whose axes are in a horizontal plane. Fig. 5 is a section of same on line 1 1. Fig. 6 is a top view of the upper toothed magnetic plate or shell which con- Fig. 12 is a vertical section at 41 4 of all of the toothed circular shells when assembled in the machine, showing the position (in dotted lines) of the bobbins and shuttles and the direction of their respective threads. Fig. 13 is an enlarged top view of one of the shuttles which is magneticallyacted upon. Fig. 14 is a section of same at 5 5. Fig. 15 is a detached view of the circular guide-spring loosely inclosed and resting in the rim of the shuttle,

showing the tension-spring for the yarn.

Similar letters refer to like parts.

In the drawings, A A A A represent the four vertical standards or uprights comprised in the frame of the machine, A A giving support to the power-shafts B and 13, and the latter is revolved by means of the meshing gears b and b, the circular bands A joining the four standards of the machine, thereby producing a rigid and substantial framework.

Within the standards of the machine and resting upon suitable integral projections forming bearings a one above the other, so as to form a nest or series, are circular frustum-shaped shells or Webs D D D and R R, all provided with teeth on their peripheries, and D D D constructed to form electromagnets.

Receiving a bearing in suitable brackets on the standards A A are vertical shafts O C, provided at their upper ends with bevel-gears c c, which mesh with the gears 0 0 having a corresponding number of teeth and secured on the transverse shaft B. Gears of suitable size, d, are secured to the vertical shafts O G and mesh with the teeth'd of the circular web-shells D, and gears d mesh with the teeth 0" of the circular web-shells R, each of the plates R B being supplied with an even number of spools h for holding one set of threads h, and their trunnions receive a bearing in vertically-slotted upright integral ears 7 of the said shells.

Resting loosely between and conforming to the disk-shaped recesses or depressions d are shuttles g, in which are wound the threads g of the shells D, and each of the said shells is constructed with a circumferential groove (1 that is wound with wire in such a manner that, by means of being traversed with an electric current, will convert the said shells D into strong electromagnets at predetermined intervals when the machine is in operation.

The intermediate or double-faced shell D is constructed with a circumferential groove d upon both its upper and lower faces.

Secured to the under sides of the magnetic shells D D D, diametrically opposed, are contact-plates l, insulated from the said shells and connected to the winding-Wire by means of the wire 70.

Projecting from suitable metallic plates m, insulated and secured to the standards A A A A, are flexible brushes or current-conducting springs n, that bear against the under side of the contact-plates 1 their entire length, the plates on being electrically connected in circuit by means of the wires 0 with the source of electrical supply G. Guides r formed by integral vertical projections, serve to direct the threads h from the spools 7L. Depressions or recesses d are formed in the face of the inner rim of the magnetic shells D,through which to pass the shuttles g to and from their seats (1 when desirable.

The shuttles g, magnetically operated upon in the machine, are constructed with a circumferential spring q, that loosely fits within the edges of the convex sides and forms the guide for the thread g of each shuttle, and to this spring is attached an auxiliary spring 7, that bears against the unused thread and forms the tension for it. A drag-wheel s on the shaft B removes the woven tube 1) or covered wire to as fast as manufactured, its speed to be regulated by the gears 19 Z), as shown, or the use of intermediate gears that will suit the speed and character of manufacture.

In the operation of the machine power is applied to the shaft B in any well-known manner, which is communicated by means of the bevel-gears to the vertical shafts C C,

which in turn by means of the gears mesh- I in g with the toothed shells rotates the latter,

the shells marked D revolving in one direction and those marked R in a directly opposite one. The threads g coming from the magneticallyaffected shuttle lying loosely between the magnetic shells are directed to the center and those threads h coming from the horizontal bobbins are first directed to the guides and thence to the center also.

In the course of the revolution of the electromagnetic shells at diametrically radial points the brushes or springs n engage the contact plates 6, carried by the magnetic shells, thus closing the circuit through the plates m on the standards, as described, and

will magnetically charge said shell and cause the latter to instantly attract the shuttles g, first up, then down, away from the opposite plate, While the threads from the horizontal bobbins h will pass over or under the threads from the shuttles g, according as the shuttle is held up or down by the attraction of the electromagnets 7t, carried by the shells D D.

The number of shuttles resting upon their sides in the depressions in the electromagnetic shells directly central 'with the wire windings correspond in number to the horizontal bobbins carried by the non-magnetic shells, so that while the threads from the horizontal bobbins pass under the threads of the vertical shuttles at one instant the following instant the same threads will pass over. It is simply necessary to increase the number of magnetic and non-magnetic shells inthe ratio shown in the nest to be able to place any num ber of plaits or braids in the weave.
